HELP - Brain receding from skeleton

[dollarPit]

Hi all - After about a year into a maturing tank I was met with a disaster as a failed Marineland Stealth Pro Heater electrocuted most of my coral and inverts (if you have this Marineland will file a claim...I'll let you know if it comes through).

I thought things have stabilized, but a few weeks later my brain coral is receding. Any advise - it seems to be receding from one side. Can I frag it to save some pieces? If so, any links on how I should be doing this?

Question 2 - On the left edge you can see the empty heads of an anchor coral - one head survives and the extension looks good...if I leave the skeleton will polyps ever propagate to the empty heads?

Water parameters
Alk 8.6
CA 410
Mg 1300

You probably want to post this in the LPS forum.

Have you run any polyfilter to see if there are contaminants in the tank?

Do you feed these corals? LPS likes food in the water.

oops - re-posted to LPS...thanks for pointing that out.

My feeding is the same - target feeding of BRS reef chili, rod's reef food. I do run carbon but can try a poly. Hard for me to tell if this is related to the electrocution or something new since things were going well and stable before the incident.
